Abstract

The aim of present study was to evaluate the effects of fish meal replacement with sunflower meal on growth, hematological indices and plasma biochemistry of common carp fingerlings. Fish with average weight of 3.03±0.36g were fed for 10 weeks by five diets including replacement levels of 0, 25, 50, 75 and 100% of fish meal with sunflower meal. Finally, blood samples were taken from caudal vein and hematological indices including red and white blood cells (WBC), differential count of WBC, hemoglobin, hematocrit, mean corpuscular volume, mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration and some biochemical parameters of plasma including triglyceride, cholesterol and glucose were determined. Based on the results, 25 and 100% treatments had significant increase and decrease in final weight, respectively (P<0.05). Differences between treatments in all hematological indices were not significant (P>0.05). In plasma biochemical parameters, there was significant decline in triglyceride level in 100% treatment (P<0.05) and cholesterol was significantly higher in control (P<0.05), but in glucose content, difference was not significant among treatments (P>0.05). According to the results of this study, replacement of fish meal with sunflower meal in common carp fingerlings diet up to 75% is suggested.
